COMPOUND FOR FILLING VEHICLE-TIRES.

No. ocean.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed March 9, 1908. Serial No. 419,984.

To an whom it may concwm:

Be it known that we, James F. WEST, FnAnK S. lllas'rnns, and \VILLIAM E. L011, citizens of the United States, residing at Brookville, in the county of Franklin and State of Indians, have invented certain new and useful Improvements in Compounds for Filling Vehicle-Tires, of which the following is a specification.

Our invention relates to compounds for filling vehicle-tires, and it has for its object the. production of a compound which can be used in the filling of the tires of vehicles of all classes. but especially those of automobiles and bicycles, and by which tires so filled may be substituted for -those filled with air under pressure and known as pnelr matic tires and which are objectionable owing to their liability to puncture, as Well as to bursting under the pressure'with which the air is confined therein.

To this end we. have produced a compound or filling for vehicle-tires which is unaffected by extremes of temperature, and which will not harden or become soft but remains of the jelly-like consistency necessary to cause it to render eflicient service. It is of such consistency that the puncturing of the tire tube filled therewith by the points of sharp objects. such as nails, tacks or glass, will not affect. the running qualities of such tire.

Our filling compound forms a mass suliicicntly elastic to yield under pressure and to take up the jar or shock due to the striktires but also that of the vehicle by relicvin it of the stress and strain incident to sue jarrin \Viti these and other objects in view our tire filling compound which we employ is made from the following enumerated ingredients which, when assembled together in the manner and a prolpriate proportions given we have 'foun wi produce a compound possessing the properties desired, same being as follows: lue, gelatin, glycerin, kaolin, formaldehyt e, and water. In producing a given quantit the proportions are: glue four ounces; atin two ounces, glycerin four ounces, kao in two ounces, and; water six ounces. he lue is dissolved in the water and the gelatin in the glycerin and the two latter ingredients added to the first two; the kaolin is then added, and the whole is heated and thoroughly stirred and mixed until all lumps are dissolved. The

stated quantity of formaldehyde is then added. v

The liquid compound thus prepared is applied to the. interior of the tire tube by pumping the same therein while in a heated condition, and when it has become cold therein the tire is in condition for use.

What we claim is:

An elastic filling compound for vehicletires comprising glue, gelatin, glycerin, kaolin, water, and formaldehyde in substantiallythe pro ortions set forth.

In testimony w ereof we aflix our signatures in presence of two witnesses; 1
